Classical T Tauri stars: magnetic fields, coronae, and star-disc interactions

C. P. Johnstone, M. Jardine, S. G. Gregory +2

The magnetic fields of young stars set their coronal properties and control their spin evolution via the star-disc interaction and outflows. Using 14 magnetic maps of 10 classical…

Planetary protection in the extreme environments of low-mass stars

A. A. Vidotto, M. Jardine, J. Morin +3

Recent results showed that the magnetic field of M-dwarf (dM) stars, currently the main targets in searches for terrestrial planets, is very different from the solar one, both in t…

Can we predict the magnetic properties of PMS stars from their H-R diagram location?

S. G. Gregory, J. -F. Donati, J. Morin +4

Spectropolarimetric observations combined with tomographic imaging techniques have revealed that all pre-main sequence (PMS) stars host multipolar magnetic fields, ranging from str…

The magnetosphere of the close accreting PMS binary V4046 Sgr AB

S. G. Gregory, V. R. Holzwarth, J. -F. Donati +14

We present a preliminary 3D potential field extrapolation model of the joint magnetosphere of the close accreting PMS binary V4046 Sgr. The model is derived from magnetic maps obta…

The magnetosphere of the close accreting PMS binary V4046 Sgr

S. G. Gregory, V. R. Holzwarth, J. -F. Donati +14

V4046 Sagittarii AB is a close short-period classical T Tauri binary. It is a circularised and synchronised system accreting from a circumbinary disk. In 2009 it was observed as pa…

A small survey of the magnetic fields of planet-host stars

Rim Fares, Claire Moutou, Jean-François Donati +5

Using spectropolarimetry, we investigate the large-scale magnetic topologies of stars hosting close-in exoplanets. A small survey of ten stars has been done with the twin instrumen…

Effects of M dwarf magnetic fields on potentially habitable planets

A. A. Vidotto, M. Jardine, J. Morin +3

We investigate the effect of the magnetic fields of M dwarf (dM) stars on potentially habitable Earth-like planets. These fields can reduce the size of planetary magnetospheres to…

Influence of surface stressing on stellar coronae and winds

M. Jardine, A. A. Vidotto, A. van Ballegooijen +4

The large-scale field of the Sun is well represented by its lowest energy (or potential) state. Recent observations, by comparison, reveal that many solar-type stars show large-sca…
